Moreover, researchers have determined that a person’s mood (which can also be an indicator of a larger illness) triggers a dog’s sense of smell. Human emotions manifest physically in chemosignals that are emitted by the body, and our pups are adept at deciphering those changes.

Their superior nose aside, dogs also gather information about a person from their voice. A few years ago, scientists discovered that dogs have an area of the brain, similar to one found in humans, that allows them to analyze emotional cues in the tone of a speaker’s voice, beyond what they’d be able to pick up from familiar words alone. A person’s voice, for example, can indicate depression, lethargy, or other bad feelings.
